The hypothesis was tested that plaque, as a complex soil comprising microorganisms, cell debris, salivary deposits and other ill-defined organic and inorganic components, would be susceptible to removal by a rinse with high detersive action. A rinse was prepared based on the principles applied to formulation of products for cleansing biologic surfaces, including anionic and nonionic surfactants, sodium benzoate, and auxiliary cleansing agents. Subjects randomly selected from a dental clinic population were scored for plaque area on the lingual and buccal surfaces of the Ramfjord teeth using the Turesky modification of the Quigley-Hein Index. The subjects then rinsed 30 seconds with 15 ml of product, and stainable plaque area was scored again. The rinsing reduced average plaque scores by an average of 13-20%, a very high level of significance. A placebo rinse and a conventional mouthwash removed 2.0% and 1.3% stainable plaque, respectively. The experimental rinse substantially Increased the number of surfaces that were totally free of plaque.</p>","PeriodicalId":77590,"journal":{"name":"Practica odontologica","volume":"11 10","pages":"17-9, 22-4, 26"},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13286169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both materials were applied on separate hemisections of the canal during 15 minutes intervals, with two applications on each canal. Rc-Prep was observed to have a slight, not significant advantage over Largal-Ultra in its cleansing effect over the dentine smear, although the compact, granular and amorphous layer of dentine smear over the root canal wall, blocking the entry to dentine channels, persisted after use of both products. In view of conditions observed in the dentine walls, the authors assume that adhesion and adaptation of obturating materials over these structures is exceedingly difficult. Although variability was not considered as is usual in clinical studies, in vitro evaluation as observed in this study allows a more accurate comparative analysis, since it was performed on one individual tooth, with analogous instrumentation and on dentary tissue with similar characteristics.</p>","PeriodicalId":77590,"journal":{"name":"Practica odontologica","volume":"11 10","pages":"31-2, 34-6"},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13286170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
